HUBBLE SPACE TELESCOPE
DAILY REPORT #1026
PERIOD COVERED: 0800 EST
Daily Status Report as of 335/1200Z.
1.0 ACTIVITIES SCHEDULED AND ACCOMPLISHED:
1.1 Completed WFC 5076 (WF/PC Cycle 3 Calibration: WFC Flats Wide. 2)
Routine Earth flat calibration exposures were taken with the Wide
Field Camera. The observations were monitored in the OSS, and the
data quality was assessed. No problems were reported.
1.2 Completed Two Sets of WFC 4381 (HST Medium - Deep Survey - Cycle 3)
The Wide Field Camera was used to make two set of medium-deep high
latitude sky survey observations taken in parallel with the prime
science observations. The observations were executed as scheduled,
and both images were reported to look normal.
1.3 Completed WFC 5269 (Partial Repeat of WF/PC Cycle 2 Interchip
Photometric Calibration)
The Wide Field Camera was used to observe standard star BD+75D325 to
calibrate the DQE (The Detector Quantum Efficiency Factor) of each
of the WFC's chips. A total of eight images were received and
displayed. All eight images were reported to be normal.
1.4 Completed Two Sets of PC 4770 (WF/PC Cycle 2 Calibration: Internal
Monitor Proposal)
The Wide Field Camera was used to make bias and dark calibration
images. These data are required for routine calibration of the
instrument and for data reduction purposes. A total of seven images
were received and displayed. All seven of the observations were
reported to be normal calibration images.
1.5 Completed PC 4644 (The Nuclei of Nearby S0 and Spiral Galaxies - I A
PC Snapshot Imaging)
The Planetary Camera was used to make one snapshot observation of
the spiral galaxy NGC-7741. The observations used filter F555W and
chip PC6. The exposure lasted 300 seconds. The observations was
received and displayed, and it was reported to look normal.
1.6 Completed FOS/BL 4673 (Ultraviolet Interstellar Polarization -
Cycle 3 High)
The Faint Object spectrograph (Blue side) was used to make
ultraviolet polarization observations of star HD99872 to make
studies of the interstellar medium. The OSS monitored the
observations, and assessed the data quality. No anomalies were
noted.
1.7 Completed GHRS/2 4541 (Cepheid Masses - Cycle 3 High)
The High Resolution Spectrograph was used to make spectral
observations of the blue main sequence star which is a companion to
Cepheid variable star HD66951. This is to help determine the mass
ratio of the two stars. The observations were executed as scheduled,
and no problems were reported.
1.8 Completed FOC/96 4674 (" Molecular Emission on HH 47 - Cycle 3 High)
The High Resolution Spectrograph was used to make observations of
Herbig - Haro Object (HH47). The HRS spectrum should contain a
strong
florescence feature at 1272 A0 (Driven by Lyman - Alpha) an
unidentified line at 1284 A0, and possibly another florescence line
at 1293 A0. The observations were executed in Fine Lock with no
apparent problems.
1.9 Completed PC 4902 (HST Medium - Deep Survey - Part 2 Low Latitude -
Cycle 3 High)
The Planetary Camera was used to make a long exposure taken in
parallel with the prime science observation. Areas of interest are
galactic structure and evolution. There is also the possibility of
serendipitous discoveries. The observation was received and
displayed in the OSS. It was reported to look okay.
1.10 Completed WFC 4929 (WF/PC Cycle 2: Improved Dark Calibration)
The Planetary Camera was used to make two dark calibration images.
The two exposures lasted 1200 seconds each, and the camera was
pre-flashed before the observations. Both observations were reported
to be normal exposures.
1.11 Completed FOC/96 3801 (Spectropolarimetry of Low Red-Shift Active
Galactic Nuclei)
The Faint Object Camera was used to make observations of quasar
0114-089 to measure the levels of its ultraviolet flux, to see if
the flux levels are high enough for subsequent observations using
the GHRS and FOS. The observations were executed as scheduled, and
no problems were reported.
1.12 Completed FOS/RD 3448 (Ultraviolet Evolution of Elliptical Galaxies
at Moderate Redshifts)
The Faint Object Spectrograph (Red Side) was used to to make
ultraviolet observations of the high red shifted elliptical galaxy
A-370-10 to look for changes in the "UV rising branch". This feature
is expected to change rapidly with the redshift of the galaxy, and
should provide information on the hot stars which are believed to
produce it. The observations were monitored in the OSS, and the data
quality was assessed. No anomalies were reported.
